    I work on some old Johnson/Evinrudes. Is the water pump impeller any more difficult to change?

    Don’t know if you have gotten anywhere with this yet. The impeller change is not bad in a Merc 9.8. It is similar to changing one in an OMC motor. They are small and tend to not be as tolerant of sitting still as the long vane OMC impellers from the classics. They seem to take a set quite quickly and require more frequent replacement in my experience.
